ABSTRACT: Previous research offers equivocal results regarding the effect of social networking site use on individuals’ self-esteem. We conduct a systematic literature review to examine the existing literature and develop a theoretical framework in order to classify the results. The framework proposes that self-esteem is affected by three distinct processes that incorporate self-evaluative information: social comparison processes, social feedback processing, and self-reflective processes. Due to particularities of the social networking site environment, the accessibility and quality of self-evaluative information is altered, which leads to online-specific effects on users’ self-esteem. Results of the reviewed studies suggest that when a social networking site is used to compare oneself with others, it mostly results in decreases in users’ self-esteem. On the other hand, receiving positive social feedback from others or using these platforms to reflect on one’s own self is mainly associated with benefits for users’ self-esteem. Nevertheless, inter-individual differences and the specific activities performed by users on these platforms should be considered when predicting individual effects.
Introduction
Social networking sites (SNSs) have become a central part of today’s life. As of April 2019, Facebook, the most popular SNS, had 2.3 billion users worldwide, while Instagram and Twitter count 1.0 and 0.3 billion users, respectively (Statista, 2019 Statista. (2019, May 28). Most popular social networks worldwide as of April 2019, ranked by number of active users (in millions). Retrieved from https://www.statista.com/statistics/272014/global-social-networks-ranked-by-number-of-users/). SNSs allow members to interact with others in a virtual field through messages and shared identity information (Chen, Fan, Liu, Zhou, & Xie, 2016 Chen, W., Fan, C.-Y., Liu, Q.-X., Zhou, Z.-K., & Xie, X.-C. (2016). Passive social network site use and subjective well-being: A moderated mediation model. Computers in Human Behavior, 64, 507–514. doi:10.1016/j.chb.2016.04.038 ). Motivated by the popularity of these platforms worldwide, the effects of SNS use on users’ well-being have been researched (e.g., Burke & Kraut, 2016 Burke, M., & Kraut, R. E. (2016). The relationship between Facebook use and well-being depends on communication type and tie strength. Journal of Computer-Mediated Communication, 21(4), 265–281. doi:10.1111/jcc4.12162 ; Kross et al., 2013 Kross, E., Verduyn, P., Demiralp, E., Park, J., Lee, D. S., Lin, N., … Ybarra, O. (2013). Facebook use predicts declines in subjective well-being in young adults. PloS One, 8(8), e69841. doi:10.1371/journal.pone.0069841 ; Valkenburg, Peter, & Schouten, 2006 Valkenburg, P. M., Peter, J., & Schouten, A. P. (2006). Friend networking sites and their relationship to adolescents’ well-being and social self-esteem. CyberPsychology & Behavior, 9(5), 584–590. doi:10.1089/cpb.2006.9.584 ) and reviewed (e.g., Huang, 2017 Huang, C. (2017). Time spent on social network sites and psychological well-being: A meta-analysis. Cyberpsychology, Behavior, and Social Networking, 20(6), 346–354. doi:10.1089/cyber.2016.0758 ) extensively.
Within this literature, self-esteem, as an important predictor of well-being (Diener & Diener, 1995 Diener, E., & Diener, M. (1995). Cross-cultural correlates of life satisfaction and self-esteem. Journal of Personality and Social Psychology, 68(4), 653–663. doi:10.1037/0022-3514.68.4.653 ), has been a topic of interest either on its own (e.g., Gonzales & Hancock, 2011 Gonzales, A. L., & Hancock, J. T. (2011). Mirror, mirror on my Facebook wall: Effects of exposure to Facebook on self-esteem. Cyberpsychology, Behavior, and Social Networking, 14(1–2), 79–83. doi:10.1089/cyber.2009.0411 ; Vogel, Rose, Roberts, & Eckles, 2014 Vogel, E. A., Rose, J. P., Roberts, L. R., & Eckles, K. (2014). Social comparison, social media, and self-esteem. Psychology of Popular Media Culture, 3(4), 206–222. doi:10.1037/ppm0000047) or as a mediator in the relationship between SNS use and well-being (Chen et al., 2016 Chen, W., Fan, C.-Y., Liu, Q.-X., Zhou, Z.-K., & Xie, X.-C. (2016). Passive social network site use and subjective well-being: A moderated mediation model. Computers in Human Behavior, 64, 507–514. doi:10.1016/j.chb.2016.04.038 ). Defined as an individual’s subjective value judgment of the self (Rosenberg, 1965 Rosenberg, M. (1965). Society and the adolescent self-image. Princeton, NJ: Princeton University Press.), self-esteem has important implications for various life outcomes, such as health (e.g., Sowislo & Orth, 2013 Sowislo, J. F., & Orth, U. (2013). Does low self-esteem predict depression and anxiety? A meta-analysis of longitudinal studies. Psychological Bulletin, 139(1), 213–240. doi:10.1037/a0028931 ), relationship satisfaction (Shackelford, 2001 Shackelford, T. K. (2001). Self-esteem in marriage. Personality and Individual Differences, 30(3), 371–390. doi:10.1016/S0191-8869(00)00023-4 ), and job performance (Judge & Bono, 2001 Judge, T. A., & Bono, J. E. (2001). Relationship of core self-evaluations traits–self-esteem, generalized self-efficacy, locus of control, and emotional stability–with job satisfaction and job performance: A meta-analysis. Journal of Applied Psychology, 86(1), 80–92. ). Dynamic in nature, self-esteem can be seen as a barometer of individual successes and failures, as well as acceptance and rejection by others (Baldwin & Sinclair, 1996 Baldwin, M. W., & Sinclair, L. (1996). Self-esteem and “If … Then” contingencies of interpersonal acceptance. Journal of Personality and Social Psychology, 71(6), 1130–1141. doi:10.1037/0022-3514.71.6.1130 ). We denote this dynamic tracking and evaluation process by the term “self-esteem updating”. Information about the self, collected both through interactions with the social environment and introspection, serve as a basis for self-esteem updating. This self-evaluative information, processed through individual self-esteem updating, therefore defines the level of a person’s self-esteem.
As communication and interaction with other individuals via SNSs play an ever-growing role in peoples’ day-to-day lives, the question arises whether these dynamics lead to particular outcomes of self-esteem updating. Indeed, existing empirical research suggests that SNS use is associated with alterations in self-esteem. For example, some studies report a positive association between SNS use and self-esteem (e.g., Gonzales & Hancock, 2011 Gonzales, A. L., & Hancock, J. T. (2011). Mirror, mirror on my Facebook wall: Effects of exposure to Facebook on self-esteem. Cyberpsychology, Behavior, and Social Networking, 14(1–2), 79–83. doi:10.1089/cyber.2009.0411 ; Valkenburg et al., 2006 Valkenburg, P. M., Peter, J., & Schouten, A. P. (2006). Friend networking sites and their relationship to adolescents’ well-being and social self-esteem. CyberPsychology & Behavior, 9(5), 584–590. doi:10.1089/cpb.2006.9.584 ), while others find negative (e.g., Vogel et al., 2014 Vogel, E. A., Rose, J. P., Roberts, L. R., & Eckles, K. (2014). Social comparison, social media, and self-esteem. Psychology of Popular Media Culture, 3(4), 206–222. doi:10.1037/ppm0000047) or insignificant (Muench, Hayes, Kuerbis, & Shao, 2015 Muench, F., Hayes, M., Kuerbis, A., & Shao, S. (2015). The independent relationship between trouble controlling Facebook use, time spent on the site and distress. Journal of Behavioral Addictions, 4(3), 163–169. doi:10.1556/2006.4.2015.013 ) relationships. This ambiguous pattern of results resembles extant research in the area of SNS use and general well-being. Some authors in this field suggest to distinguish different SNS activities (for an overview see Huang, 2017 Huang, C. (2017). Time spent on social network sites and psychological well-being: A meta-analysis. Cyberpsychology, Behavior, and Social Networking, 20(6), 346–354. doi:10.1089/cyber.2016.0758 ), such as social connection promoting vs. non-promoting activities (Clark, Algoe, & Green, 2018 Clark, J. L., Algoe, S. B., & Green, M. C. (2018). Social network sites and well-being: the role of social connection. Current Directions in Psychological Science, 27(1), 32–37. doi:10.1177/0963721417730833 ) or active and passive use patterns (e.g., Verduyn, Ybarra, Résibois, Jonides, & Kross, 2017 Verduyn, P., Ybarra, O., Résibois, M., Jonides, J., & Kross, E. (2017). Do social network sites enhance or undermine subjective well-being? A critical review. Social Issues and Policy Review, 11(1), 274–302. doi:10.1111/sipr.2017.11.issue-1 ) to analyze the beneficial or harmful effects of SNS use on well-being. However, it remains to be seen if these approaches can be transferred to the concept of self-esteem. Scientific results in the field of SNS use and self-esteem still remain scattered and ambiguous (Liu & Baumeister, 2016 Liu, D., & Baumeister, R. F. (2016). Social networking online and personality of self-worth: A meta-analysis. Journal of Research in Personality, 64, 79–89. doi:10.1016/j.jrp.2016.06.024 ), and so far no theory has been established that integrates both social and internal processes to explain these diverging findings.
To close this research gap, we conduct a systematic literature review to make sense of the growing body of research in this area (e.g., Levy & Ellis, 2006 Levy, Y., & Ellis, T. (2006). A systems approach to conduct an effective literature review in support of information systems research. Informing Science, 9, 181–212. doi:10.28945/479; Webster & Watson, 2002 Webster, J., & Watson, R. T. (2002). Analyzing the past to prepare for the future: Writing a literature review. MIS Quarterly, 26(2), xiii–xxiii. ). In doing so, we contribute to the existing literature as follows: first, by reviewing the most common self-esteem theories, we propose that self-esteem updating is mainly driven by three processes: (1) social comparison, (2) social feedback processing, and (3) self-reflection. These three processes incorporate self-evaluative information gathered from an individual’s social environment or by introspection based on information about the self. Based on our framework, we can explain the equivocal results, unifying the positive and negative findings. Moreover, we are able to depict knowledge gaps and give recommendations for future research. Second, we contribute to the growing body of research which studies the implications of information technology use for individuals’ well-being (e.g., Burke & Kraut, 2016 Burke, M., & Kraut, R. E. (2016). The relationship between Facebook use and well-being depends on communication type and tie strength. Journal of Computer-Mediated Communication, 21(4), 265–281. doi:10.1111/jcc4.12162 ; Krasnova, Widjaja, Buxmann, Wenninger, & Benbasat, 2015 Krasnova, H., Widjaja, T., Buxmann, P., Wenninger, H., & Benbasat, I. (2015). Research note—why following friends can hurt you: An exploratory investigation of the effects of envy on social networking sites among college-age users. Information Systems Research, 26(3), 585–605. doi:10.1287/isre.2015.0588 ; Kross et al., 2013 Kross, E., Verduyn, P., Demiralp, E., Park, J., Lee, D. S., Lin, N., … Ybarra, O. (2013). Facebook use predicts declines in subjective well-being in young adults. PloS One, 8(8), e69841. doi:10.1371/journal.pone.0069841 ). Specifically, we discuss the role of SNSs as a source of self-evaluative information, driving the association between their use and self-esteem. Third, and on a more global level, our review is in line with the initiative of an Internet-based information and communication technologies (ICT)-enabled “Bright Society” that aims at protecting society from potential risks of technology use (Fedorowicz et al., 2015 Fedorowicz, J., Agarwal, R., Lee, G., Lee, J. K., Watson, R., & Zhang, P. (2015). The AIS grand vision project: What, why, and how. Presented at the Americas Conference on Information Systems (AMCIS), Puerto Rico. ; Lee, 2015 Lee, J. K. (2015). Guest editorial: research framework for AIS grand vision of the bright ICT initiative. MIS Quarterly, 39(2), iii–xii. ). Indeed, while the use of SNSs has been increasingly associated with “dark sides” (Lee, 2016 Lee, J. K. (2016). Invited Commentary—Reflections on ICT-enabled Bright Society Research. Information Systems Research, 27(1), 1–5. doi:10.1287/isre.2016.0627), our study provides evidence that certain types of SNS use are beneficial for users’ self-esteem and should therefore be encouraged.
The paper is structured as follows: first, we provide an overview of theories of self-esteem and derive our theory-driven framework on self-esteem updating. In the next step, we discuss SNSs’ potential meaning as a source of self-evaluative information by explaining how their functionalities can determine both the quality and the access to self-evaluative information relevant for self-esteem. This helps us to frame self-esteem updating in the SNS environment in relation to existing SNS functionalities. Based on this, we propose the directionality of the effect of each process on self-esteem updating in the SNS environment. Consequently, we aim to test our propositions based on findings collected through a literature review on the topic of self-esteem and SNS use. After explaining the applied methodology, we continue with the presentation of the results of our review. We show that all three processes have been investigated to a varying extent by research: while processes related to (1) social comparison mainly result in adverse effects on self-esteem, (2) social feedback processing, and (3) self-reflective processes have the potential to increase the self-esteem of an individual. However, there is evidence that personality traits moderate the effect between SNS use and self-esteem, which might explain prevalent contradictory findings. Based on these insights, we discuss our results in the final chapter and provide concluding remarks.
Background and theoretical framework
In this section, we first define the concept of self-esteem and present our general theory-driven framework on self-esteem updating. We then link our framework with existing functionalities on SNSs to highlight the particularities prevalent in the online context, which affect the processes of our framework.
Self-esteem
Dynamic in nature, the concept of self-esteem refers to a subjective value judgment about one’s self (Baldwin & Sinclair, 1996 Baldwin, M. W., & Sinclair, L. (1996). Self-esteem and “If … Then” contingencies of interpersonal acceptance. Journal of Personality and Social Psychology, 71(6), 1130–1141. doi:10.1037/0022-3514.71.6.1130 ; Rosenberg, 1965 Rosenberg, M. (1965). Society and the adolescent self-image. Princeton, NJ: Princeton University Press.). While low self-esteem has been linked to a number of risks for mental health (e.g., Sowislo & Orth, 2013 Sowislo, J. F., & Orth, U. (2013). Does low self-esteem predict depression and anxiety? A meta-analysis of longitudinal studies. Psychological Bulletin, 139(1), 213–240. doi:10.1037/a0028931 ), high self-esteem has been shown to have a protective role, helping people to cope with potential risks, such as negative feedback, setbacks, or other sorts of failures (Dumont & Provost, 1999 Dumont, M., & Provost, M. A. (1999). Resilience in adolescents: Protective role of social support, coping strategies, self-esteem, and social activities on experience of stress and depression. Journal of Youth and Adolescence, 28(3), 343–363. doi:10.1023/A:1021637011732 ). Due to the importance of self-esteem as a resource to cope with day-to-day challenges, people have the basic need to maintain and enhance their self-esteem. This need can be fulfilled through continuous processing of information from their social environment (Greenberg, Pyszczynski, & Solomon, 1986 Greenberg, J., Pyszczynski, T., & Solomon, S. (1986). The causes and consequences of a need for self-esteem: A terror management theory. In R. F. Baumeister (Ed.), Public self and private self (pp. 189–212). New York, NY: Springer-Verlag.). Referred to as self-esteem updating, the formation of self-esteem can therefore be seen as an ongoing dynamic process. Information that is used for this process is called self-evaluative information (e.g., Wayment & Taylor, 1995 Wayment, H. A., & Taylor, S. E. (1995). Self-evaluation processes: Motives, information use, and self-esteem. Journal of Personality, 63(4), 729–757. doi:10.1111/jopy.1995.63.issue-4 ).
Several theories describe how and which kind of self-evaluative information is processed and ultimately influences individual self-esteem (e.g., Bem, 1967 Bem, D. J. (1967). Self-perception: An alternative interpretation of cognitive dissonance phenomena. Psychological Review, 74(3), 183–200. doi:10.1037/h0024835 ; Festinger, 1954 Festinger, L. (1954). A theory of social comparison processes. Human Relations, 7(2), 117–140. doi:10.1177/001872675400700202 ; Leary, 1999 Leary, M. R. (1999). Making sense of self-esteem. Current Directions in Psychological Science, 8(1), 32–35. doi:10.1111/1467-8721.00008 ). In order to systematically understand the process of self-esteem updating, we review the most common self-esteem theories to our knowledge and group them according to the overall type of self-evaluative information they incorporate (for an overview see Appendix A). By doing so, we are able to identify three routes that individuals might follow when processing information relevant to their self-esteem. Figure 1 illustrates our proposed model of self-esteem updating. It reflects three key processes that take place in the course of self-esteem updating: (1) social comparison processes, (2) social feedback processing, and (3) self-reflective processes.
Figure 1. Proposed model of self-esteem updating.
The first identified process refers to (1) social comparisons. This process is based on comparisons of information related to the self and information provided by other individuals. Social comparison theory (Festinger, 1954 Festinger, L. (1954). A theory of social comparison processes. Human Relations, 7(2), 117–140. doi:10.1177/001872675400700202 ) proposes that people have an ongoing basic need to evaluate themselves in relation to others in order to get an appropriate assessment of their abilities and qualities. However, individuals do not compare themselves to anybody in their social surroundings. Social comparisons mainly take place if the target of social comparison is not too different from the self and the object of social comparison is of relevance to the subject (Festinger, 1954 Festinger, L. (1954). A theory of social comparison processes. Human Relations, 7(2), 117–140. doi:10.1177/001872675400700202 ). Depending on their directionality, social comparison processes could lead to different outcomes in terms of self-esteem. For example, diminished self-esteem can be observed when individuals compare themselves to others who are better off (upward comparison). At the same time, comparing oneself to others who have lower skills or qualifications (downward comparison) is often associated with an increase in self-esteem (e.g., Morse & Gergen, 1970 Morse, S., & Gergen, K. J. (1970). Social comparison, self-consistency, and the concept of self. Journal of Personality and Social Psychology, 16(1), 148–156. doi:10.1037/h0029862 ; Thornton & Moore, 1993 Thornton, B., & Moore, S. (1993). Physical attractiveness contrast effect: Implications for self-esteem and evaluations of the social self. Personality and Social Psychology Bulletin, 19(4), 474–480. doi:10.1177/0146167293194012 ).
The second process that determines self-esteem is (2) social feedback processing. This process incorporates self-evaluative information that stems from direct interaction with other individuals and may signal either social acceptance or rejection. Individuals highly thrive for reactions from their social environment in order to appropriately estimate the degree to which they are accepted and liked by others which can be seen as one way to satisfy individuals’ need of social belonging (Baumeister & Leary, 1995 Baumeister, R. F., & Leary, M. R. (1995). The need to belong: Desire for interpersonal attachments as a fundamental human motivation. Psychological Bulletin, 117(3), 497–529. doi:10.1037/0033-2909.117.3.497 ). Sociometer Theory (Leary, 1999 Leary, M. R. (1999). Making sense of self-esteem. Current Directions in Psychological Science, 8(1), 32–35. doi:10.1111/1467-8721.00008 ) suggests that self-esteem is a barometer reflecting the social acceptance and the social rejection by others. Indeed, receiving negative feedback or any sign of social rejection from others can be seen as a massive threat to self-esteem and has been linked to several negative outcomes to individuals’ well-being, such as negative affect, anxiety, and depression (Baumeister & Leary, 1995 Baumeister, R. F., & Leary, M. R. (1995). The need to belong: Desire for interpersonal attachments as a fundamental human motivation. Psychological Bulletin, 117(3), 497–529. doi:10.1037/0033-2909.117.3.497 ; Leary, 1990 Leary, M. R. (1990). Responses to social exclusion: Social anxiety, jealousy, loneliness, depression, and low self-esteem. Journal of Social and Clinical Psychology, 9(2), 221–229. doi:10.1521/jscp.1990.9.2.221 ). On the other hand, receiving positive feedback or any sign of social acceptance benefits the evaluation of the self (Leary, 1999 Leary, M. R. (1999). Making sense of self-esteem. Current Directions in Psychological Science, 8(1), 32–35. doi:10.1111/1467-8721.00008 ).
The third identified process that influences self-esteem is (3) self-reflection. While interaction with the social environment is a critical determinant of individual self-esteem; self-esteem can also be derived from more internal aspects. Several theories aim at explaining how the reflection on these facets of the self may influence individual processes of self-esteem updating. For example, the reflection on past behavior (self-perception theory, Bem, 1967 Bem, D. J. (1967). Self-perception: An alternative interpretation of cognitive dissonance phenomena. Psychological Review, 74(3), 183–200. doi:10.1037/h0024835 ), personal standards (control theory of self-regulation, Carver & Scheier, 1981 Carver, C. S., & Scheier, M. F. (1981). The self-attention-induced feedback loop and social facilitation. Journal of Experimental Social Psychology, 17(6), 545–568. doi:10.1016/0022-1031(81)90039-1 ), images of how people would like to see themselves (self-discrepancy theory, Higgins, 1987 Higgins, E. T. (1987). Self-discrepancy: a theory relating self and affect. Psychological Review, 94(3), 319. doi:10.1037/0033-295X.94.3.319 ), important values, or other positive aspects of the self (self-affirmation theory, Steele, 1988 Steele, C. M. (1988). The psychology of self-affirmation: Sustaining the integrity of the self. In L. Berkowitz (Ed.), Advances in experimental social psychology (Vol. 21, pp.261–302). New York, NY: Academic Press.) can serve as a basis for self-evaluation and therefore impact individual self-esteem. Research in the field of self-affirmation (Steele, 1988 Steele, C. M. (1988). The psychology of self-affirmation: Sustaining the integrity of the self. In L. Berkowitz (Ed.), Advances in experimental social psychology (Vol. 21, pp.261–302). New York, NY: Academic Press.) has shown that when people think about positive facets of their selves they can experience boosts in self-esteem (Koole, Smeets, Van Knippenberg, & Dijksterhuis, 1999 Koole, S. L., Smeets, K., Van Knippenberg, A., & Dijksterhuis, A. (1999). The cessation of rumination through self-affirmation. Journal of Personality and Social Psychology, 77(1), 111–125. doi:10.1037/0022-3514.77.1.111 ). Activities with such self-affirming qualities in the offline context are, for instance, writing about one’s most important values or reading self-affirming messages (McQueen & Klein, 2006 McQueen, A., & Klein, W. M. P. (2006). Experimental manipulations of self-affirmation: A systematic review. Self and Identity, 5(4), 289–354. doi:10.1080/15298860600805325). Importantly, (3) self-reflective processes are not solely based on information about the self in isolation, but can also incorporate information about the self, gained in the course of interaction with others. In this context, it is important to distinguish (3) self-reflective processes from (2) social feedback processing, as described above. While instances of interpersonal interaction can be reflected on multiple times within the process of self-reflection, processing of social feedback focuses on a single episode of social interaction (e.g., getting complimented by an acquaintance).
Taken together, (1) social comparison, (2) social feedback processing, and (3) self-reflection incorporate self-evaluative information, and therefore influence self-esteem updating in everyday-life.
Our framework on self-esteem updating is grounded in a general perspective in the offline environment. However, as the three processes mainly take place in interactions between individuals, we assume that they also take place in the context of SNSs. Indeed, SNSs are largely based on social interactions, which justify the application of our framework in the online context. Since the SNS environment exhibits specific particularities, certain dynamics of communication and interaction on these platforms and the thus resulting self-evaluative information might uniquely contribute to the three processes of self-esteem updating. In the following section, we will exemplify this assumption in greater detail.
Self-evaluative information in the SNS environment
Due to its dynamic character, individual self-esteem is the result of a constant integration of self-evaluative information as part of three basic processes described above. SNSs can be seen as a rich source of such self-evaluative information. Indeed, SNS platforms allow users to easily share personal information and updates, get in contact with others, and interact with them. As a result, users are motivated to disclose a large amount of personal information, and, in turn, are constantly exposed to an abundance of information about others on the network. Against this background, we presume that the same processes of self-esteem updating mentioned above take place in the context of SNSs. Figure 2 illustrates the presumed operation of the three self-evaluative processes in the context of SNSs.
Figure 2. Processes of self-esteem updating in the context of SNSs.
For example, the information provided by other users in the SNS environment (e.g., in the form of photos, status updates, and profile descriptions) can be used for (1) social comparison processes. Users can compare relevant aspects of their selves with the information provided by others and can thus draw conclusions about their own positioning (Krasnova et al., 2015 Krasnova, H., Widjaja, T., Buxmann, P., Wenninger, H., & Benbasat, I. (2015). Research note—why following friends can hurt you: An exploratory investigation of the effects of envy on social networking sites among college-age users. Information Systems Research, 26(3), 585–605. doi:10.1287/isre.2015.0588 ). Users further have the opportunity to interact with each other (e.g., in the form of conversations, giving and receiving likes, and commenting on each other’s content). Information stemming from these interactions may be perceived as signals of social acceptance or rejection, thereby initiating (2) social feedback processing (Wenninger, Krasnova, & Buxmann, 2019 Wenninger, H., Krasnova, H., & Buxmann, P. (2019). Understanding the role of social networking sites in the subjective well-being of users: a diary study. European Journal of Information Systems, 28(2), 126–148. doi:10.1080/0960085X.2018.1496883). Finally, by disclosing a myriad of information about their selves on the platforms (e.g., by providing detailed profile descriptions and sharing meaningful moments of their lives in the form of photos, videos, and status updates), (3) self-reflective processes are likely to be activated. Specifically, by reflecting on their self-provided information or on former interactions with others on a SNS, users can draw conclusions about how to see and evaluate themselves (Gonzales & Hancock, 2011 Gonzales, A. L., & Hancock, J. T. (2011). Mirror, mirror on my Facebook wall: Effects of exposure to Facebook on self-esteem. Cyberpsychology, Behavior, and Social Networking, 14(1–2), 79–83. doi:10.1089/cyber.2009.0411 ).
As an exemplary illustration of these processes, imagine an SNS user who is very active in sports. On the one hand, processing information provided by others (e.g., a picture of an acquaintance showing her winning a marathon) could lead this user to the following (1) social comparison process outcome: “I am less athletic than my acquaintance”. On the other hand, when this user gets immediate feedback in form of likes after posting her workout picture, a possible outcome of (2) social feedback processing could be “Others value that I am active”. Further, browsing her own profile that incorporates photos of her own marathon experience, the same user might conclude: “I think that I am very athletic”; this would be an outcome of a (3) self-reflective process. While self-esteem might decrease in the first case, it potentially increases in the latter two.
Importantly, while social encounters may contribute to changes in individual self-esteem online and offline, we propose that there are specific particularities of the SNS environment. These particularities are reflected in the quality and accessibility of self-evaluative information, and may therefore uniquely affect the three processes of self-esteem updating and their final outcome. Table 1 gives an overview of the particularities of self-evaluative information in the SNSs environment, lists respective enabling SNS features, and empirical evidence.
Table 1. Particularities of self-evaluative information on SNSs.

Specifically, the main particularities of self-evaluative information incorporated in (1) social comparison processes are the following: While social comparisons frequently happen in the offline domain as well, users of SNSs have a comparably larger and more accessible pool of subjects to compare with (Smith, 2014 Smith, A. (2014, February 3). What people like and dislike about Facebook. Retrieved from http://www.pewresearch.org/fact-tank/2014/02/03/what-people-like-dislike-about-facebook/). Users can access comparison triggering information easily with information on others’ news, status updates, photos, and links always within reach. Furthermore, SNS algorithms selectively present personalized content to users that raise the frequency of seeing information in subjectively relevant comparison domains (Bucher, 2012 Bucher, T. (2012). Want to be on the top? Algorithmic power and the threat of invisibility on Facebook. New Media & Society, 14(7), 1164–1180. doi:10.1177/1461444812440159 ). This increases the likelihood of comparisons with others (Tesser, 1988 Tesser, A. (1988). Toward a self-evaluation maintenance model of social behaviorIn Advances in experimental social psychology (Vol. 21, pp. 181–227). New York, NY: Academic Press. Retrieved from http://linkinghub.elsevier.com/retrieve/pii/S0065260108602270). In addition, comparisons in the SNS environment are mostly upward (Vogel et al., 2014 Vogel, E. A., Rose, J. P., Roberts, L. R., & Eckles, K. (2014). Social comparison, social media, and self-esteem. Psychology of Popular Media Culture, 3(4), 206–222. doi:10.1037/ppm0000047). This can be explained by users presenting enhanced versions of themselves, facilitated through asynchronous communication, content selection, and content editing on SNSs (Ellison, Heino, & Gibbs, 2006 Ellison, N., Heino, R., & Gibbs, J. (2006). Managing impressions online: Self-presentation processes in the online dating environment. Journal of Computer-Mediated Communication, 11(2), 415–441. doi:10.1111/jcmc.2006.11.issue-2 ; Toma, Hancock, & Ellison, 2008 Toma, C. L., Hancock, J. T., & Ellison, N. B. (2008). Separating fact from fiction: An examination of deceptive self-presentation in online dating profiles. Personality and Social Psychology Bulletin, 34(8), 1023–1036. doi:10.1177/0146167208320061 ). As users mostly use SNS passively (Verduyn et al., 2015 Verduyn, P., Lee, D. S., Park, J., Shablack, H., Orvell, A., Bayer, J., … Kross, E. (2015). Passive Facebook usage undermines affective well-being: Experimental and longitudinal evidence. Journal of Experimental Psychology: General, 144(2), 480–488. doi:10.1037/xge0000057 ), the risk of engaging in social comparison is especially high. Other users’ profile pages on SNSs enable passive browsing through large amounts of stored data, thereby yielding frequent grounds for social comparisons. In consideration of these particularities of self-evaluative information on SNSs, we propose that the outcome of (1) social comparison processes on users’ self-esteem is mainly negative.
With regards to (2) social feedback processing, both the tonality and frequency of social feedback on SNSs may cause particular outcomes of users’ self-esteem: Similar to most offline social interactions, feedback from others and the tone of general interactions is mostly positive11. Although negative feedback in forms of cyberbullying, hate speech or gossiping is a phenomenon that is present on SNSs (e.g., Smith et al., 2008 Smith, P. K., Mahdavi, J., Carvalho, M., Fisher, S., Russell, S., & Tippett, N. (2008). Cyberbullying: its nature and impact in secondary school pupils. Journal of Child Psychology and Psychiatry, 49(4), 376–385. doi:10.1111/j.1469-7610.2007.01846.x ), research suggests that it is rare compared to feedback with positive tonality (Lenhart et al., 2011 Lenhart, A., Madden, M., Smith, A., Purcell, K., Zickuhr, K., & Rainie, L. (2011). Teens, Kindness and Cruelty on Social Network Sites: How American Teens Navigate the New World of” Digital Citizenship”. Pew Internet & American Life Project. Retrieved from http://pewinternet.org/Reports/2011/Teens-and-socialmedia.aspx).
(Barasch & Berger, 2014 Barasch, A., & Berger, J. (2014). Broadcasting and narrowcasting: How audience size affects what people share. Journal of Marketing Research, 51(3), 286–299. doi:10.1509/jmr.13.0238 ; Oh, Ozkaya, & LaRose, 2014 Oh, H. J., Ozkaya, E., & LaRose, R. (2014). How does online social networking enhance life satisfaction? The relationships among online supportive interaction, affect, perceived social support, sense of community, and life satisfaction. Computers in Human Behavior, 30, 69–78. ). However, low effort functionalities such as the “Like-Button” encourage users to feedback on each other not only more easily and frequently but also in a reciprocal way (Burke, Marlow, & Lento, 2010 Burke, M., Marlow, C., & Lento, T. (2010). Social network activity and social well-being. Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (pp. 1909–1912). Atlanta, GA, USA. ; Wenninger et al., 2019 Wenninger, H., Krasnova, H., & Buxmann, P. (2019). Understanding the role of social networking sites in the subjective well-being of users: a diary study. European Journal of Information Systems, 28(2), 126–148. doi:10.1080/0960085X.2018.1496883). Additionally, SNSs inherent feedback promoting features such as birthday wishes or friendship reminders prompt users to signal their social appreciation to others. Given these peculiarities, we suggest that (2) social feedback processing mainly leads to positive effects on users’ self-esteem.
Processes of (3) self-reflection in the SNS environment are mainly characterized in terms of two aspects that uniquely contribute to self-esteem. Firstly, self-provided information on SNSs is mainly positive, as SNSs allow their users to carefully select and edit the information disclosed on their own profiles and remove unflattering content shared by others (Ellison et al., 2006 Ellison, N., Heino, R., & Gibbs, J. (2006). Managing impressions online: Self-presentation processes in the online dating environment. Journal of Computer-Mediated Communication, 11(2), 415–441. doi:10.1111/jcmc.2006.11.issue-2 ; Hum et al., 2011 Hum, N. J., Chamberlin, P. E., Hambright, B. L., Portwood, A. C., Schat, A. C., & Bevan, J. L. (2011). A picture is worth a thousand words: A content analysis of Facebook profile photographs. Computers in Human Behavior, 27(5), 1828–1833. doi:10.1016/j.chb.2011.04.003 ). Secondly, the availability of information used for self-reflective processes is facilitated as it is saved and stored permanently on SNSs. Therefore, users can easily reflect upon both self-presentational information in the form of their presented self-image, as well as their interaction with others. SNS functionalities that enable browsing one’s own profile site and revisiting former interactions with and reactions from others thus foster (3) self-reflective processes by making people aware of positive facets of their self and their relationships (Nabi, Prestin, & So, 2013 Nabi, R. L., Prestin, A., & So, J. (2013). Facebook friends with (Health) benefits? Exploring social network site use and perceptions of social support, stress, and well-being. Cyberpsychology, Behavior, and Social Networking, 16(10), 721–727. doi:10.1089/cyber.2012.0521 ). Hence, we assume that due to these enabling features of SNSs, (3) self-reflective processes mainly lead to increases in users’ self-esteem.
Taken together, we assume that the above-mentioned functionalities of SNSs determine the accessibility and quality of available self-evaluative information, which thus results in detrimental effects for self-esteem in case of (1) social comparison processes and in more favorable self-esteem outcomes in cases of (2) social feedback processing, and (3) self-reflective processes. In order to support these propositions and to summarize existing literature, we conducted a systematic literature review in the area of SNS use and self-esteem. We present details of our applied methodology and its results in the following section.

Found readiness potentials before arbitrary decisions, but—critically—not before deliberate ones, supporting interpretation of readiness potentials as byproducts of accumulation of random fluctuations in arbitrary decisions
Neural precursors of deliberate and arbitrary decisions in the study of voluntary action. U. Maoz, G. Yaffe, C. Koch, L. Mudrik. bioRxiv, July 15, 2019. https://doi.org/10.1101/097626
Abstract: The readiness potential (RP)—a key ERP correlate of upcoming action—is known to precede subjects’ reports of their decision to move. Some view this as evidence against a causal role for consciousness in human decision-making and thus against free-will. Yet those studies focused on arbitrary decisions—purposeless, unreasoned, and without consequences. It remains unknown to what degree the RP generalizes to deliberate, more ecological decisions. We directly compared deliberate and arbitrary decision-making during a $1000-donation task to non-profit organizations. While we found the expected RPs for arbitrary decisions, they were strikingly absent for deliberate ones. Our results and drift-diffusion model are congruent with the RP representing accumulation of noisy, random fluctuations that drive arbitrary—but not deliberate—decisions. They further point to different neural mechanisms underlying deliberate and arbitrary decisions, challenging the generalizability of studies that argue for no causal role for consciousness in decision-making to real-life decisions.
Significance Statement: The extent of human free will has been debated for millennia. Previous studies demonstrated that neural precursors of action—especially the readiness potential—precede subjects’ reports of deciding to move. Some viewed this as evidence against free-will. However, these experiments focused on arbitrary decisions—e.g., randomly raising the left or right hand. We directly compared deliberate (actual $1000 donations to NPOs) and arbitrary decisions, and found readiness potentials before arbitrary decisions, but—critically—not before deliberate decisions. This supports the interpretation of readiness potentials as byproducts of accumulation of random fluctuations in arbitrary but not deliberate decisions and points to different neural mechanisms underlying deliberate and arbitrary choice. Hence, it challenges the generalizability of previous results from arbitrary to deliberate decisions.

Conservative and Republican women and men are thus less likely to report more severe forms of Sexual Harassment and Assault, which may explain differences in beliefs on these issues
Political Differences in American Reports of Sexual Harassment and Assault. Rupa Jose, James H. Fowler, Anita Raj. Journal of Interpersonal Violence, March 22, 2019. https://doi.org/10.1177/0886260519835003
Abstract: Political ideology has been linked to beliefs regarding sexual harassment and assault (SH&A). Using data from the January 2018 Stop Street Sexual Harassment online poll (N = 2,009), this study examined associations of political identity and political ideology with self-reported experiences of being the victim of SH&A. SH&A experiences were coded into four mutually exclusive groups: none, non-physically aggressive harassment, physically aggressive harassment, or sexual assault. Sex-stratified logistic regression models assessed associations of interest, adjusting for participant demographics. Among women, more conservative political ideology was negatively associated with reports of sexual assault, odds ratio (OR) = 0.85, 95% confidence interval (CI) = [0.74, 0.98]. Among males, more conservative political ideology was negatively associated with reports of physically aggressive sexual harassment (OR = 0.85, 95% CI = [0.73, 0.98]), and greater Republican affiliation was negatively associated with reports of sexual assault (OR = 0.82, 95% CI = [0.68, 0.99]). Conservative and Republican women and men are thus less likely to report more severe forms of SH&A, which may explain differences in beliefs on these issues. Research is needed to determine if political differences are due to reporting biases or differential vulnerabilities.

Discussion
Our results indicate that Republicans and conservatives are generally less likely to report having experienced more severe forms of sexual harassment, but more likely to report non-physically aggressive forms of harassment compared with persons with different political identities or ideologies, adjusting for relevant controls. These findings parallel poll data on reported sexual harassment by political party, where Republicans are less likely to endorse general sexual harassment compared with Democrats or Independents (Graf, 2018; Quinnipiac University, 2017). However, distinct from poll data, our results showed that political identity and ideology had differential relationships with sexual harassment or assault depending on the type experienced (i.e., non-physically aggressive harassment, physically aggressive harassment, and sexual assault) and respondent gender. Results indicated that Republicans were more likely to report non-physically aggressive harassment if female and less likely to report physically aggressive harassment if male; all Republicans irrespective of gender were less likely to report sexual assault (vs. Democrats or Independents). Conservatives were likewise less likely to report sexual assault if female and less likely to report physically aggressive harassment if male (vs. liberals or moderates). To determine the political driver of harassment or assault reporting, both political identity and ideology were included in the same model. Political ideology explained the reduced reporting of female sexual assault and male physically aggressive harassment, and political identity explained the reduced reporting of male sexual assault.
Our findings suggest that political identity and ideology, though related, are not the same. Political identity in fact had a unique effect on female nonphysically aggressive harassment and male sexual assault. In addition, with the exception of female non-physically aggressive harassment, Republican identity and politically conservative ideals were associated with a decreased chance of reporting sexual harassment and or assault. A few explanations exist as to why this might be the case. One possibility is that there may be bias in reports of experiences of harassment or assault due to the social desirability of fitting in with the perceived social views of fellow partisans (Streb, Burrell, Frederick, & Genovese, 2008). The desire to conform, be obedient, loyal, follow with tradition, and have ties to people who hold similar beliefs is more characteristic of political conservatives than liberals (Jost, van der Linden, Panagopoulos, & Hardin, 2018). This deep-set “tribe” mentality could result in conservatives or Republicans underreporting sexual violence, as acknowledgment could be disruptive to their world views and relationships. A second possibility is that political membership and ideology differences may translate to differences in awareness of more ubiquitous forms of sexual harassment (e.g., derogatory name calling) and or differences in reporting acceptance or stigma. Polling data suggest that Democrats are more willing to enforce punitive policies toward perpetrators of sexual harassment, advocate for female victims, and reflect on their own behavior toward women following recent stories about sexual harassment when compared to Republicans (Dann, 2017; Graf, 2018; Kurtzleben, 2017). To the extent that these attitudes reflect that of the larger political base, Democrats may be more comfortable in their reporting of sexual victimization compared to Republicans due to feelings of perceived group support. A third possibility is that liberals and Democrats are in fact more vulnerable to sexual harassment and assault. In a meta-analytic review, political conservatism was found to be negatively associated with openness to experience and tolerance for uncertainty but positively associated with a need for order, structure, and closure (Jost, Glaser, Kruglanski, & Sulloway, 2003). Risk perception research also finds that conservatives and Republicans are less risk-accepting than liberals and Democrats (Kam & Simas, 2010). This suggests that the environments that liberals and conservatives navigate day-to-day, and how they do so, can be different in their risk for unwanted sexual advances and contact. More research is needed to understand how political identity and political ideology influence how men and women behave socially and perceive member disclosure of sexual harassment and or assault.
Responses in the aftermath of sexual harassment or assault also indicate political differences, with Republicans less likely to change their route or routine compared with non-Republicans (irrespective of gender). Republican men also are more likely to stop a hobby or group activity but less likely to end a relationship or seek medical help compared with non-Republican men. These differences suggest that Republicans, especially Republican men, are less likely to make changes to their everyday lives or personal lives in the aftermath of abuse. In fact, except for their tendency to withdraw from extracurricular obligations, Republican men appear to carry on with “life as usual.” The lack of reported change for victimized Republican men may be a consequence of the type or reduced severity of victimization experienced, biased reporting due to self-enhancement tendencies (Wojcik, Hovasapian, Graham, Motyl, & Ditto, 2015), the types of responses assessed, or true differences in preferred behavioral practices following sexual harassment or assault. Future research is needed to better ascertain the robustness and causal mechanisms underlying these findings. Also, in light of the modern political landscape, these results suggest that more effort should be made by current leaders to include men and women, Republicans and Democrats, and liberals and conservatives in discussions about sexual harassment and violence legislation. Hearing from those at a heightened risk for sexual victimization can result in more effective and inclusive solutions to the national problem of sexual
harassment and assault (Paxton, Kunovich, & Hughes, 2007). Consistent with prior studies, we found that females, persons with a disability, and ethnic minorities (Hispanics) are more likely to report physically aggressive harassment and or sexual assault than their respective counterparts (Graf, 2018; Kearl, 2014, 2018; Martin et al., 2006; Rospenda et al., 2009). Age was found to have a curvilinear effect on female reports of sexual assault and male reports of physically aggressive harassment such that reporting increased into middle age and then declined. Non-linear age trends in tolerance for sexual harassment have been reported with young women being less tolerant than older women of sexual harassment (Ford & Donis, 1996). Age effects in reported sexual victimization may be linked to age-related differences in tolerance for sexual harassment.
Limitations exist due to the structure and specificity of our data. The cross-sectional nature of our data prohibited us from examining how political differences influenced reports of harassment or assault over time and vice versa. Political identity and ideology are not fixed attributes and can change in response to experiences of sexual victimization. Longitudinal data are required to determine the casual pathway between political identity or ideology and sexual harassment or assault. We also did not have any information regarding the severity or frequency of the reported harassment or assault. Our categorization of sexual harassment into harassment (not physically aggressive), physically aggressive harassment, and sexual assault nevertheless does provide meaningful groupings for analyses; an improvement to standard practices and a means to promote definitional clarity and loosely approximate severity. For behavioral reactions or responses assessed in relation to a “sexually harassing or abusive experience,” details regarding the incident itself remain unknown (e.g., harassment/abuse type and recency). We were thus unable to examine differences in reactions by harassment type and or generational effects. All data were self-report and therefore subject to participant reporting bias or memory inaccuracies. Data collection also occurred at two time points 4 days apart and did not include a lifetime exposure to violence measure. It is recommended that surveys on sexual harassment and assault be administered at a single time point and inquire about personal trauma history to improve methodological rigor and better adjust for differences in reporting and reactions to sexual victimization.
Sexual harassment and assault have become a core issue in contemporary society. Fueled by the 2017 #MeToo social media campaign, public discourse surrounding issues of harassment and assault are increasingly common and political. Based on our findings, we note that party differences do in fact arise when considering reporting and responses to sexual harassment and or assault. On average, Republicans and conservatives are less likely to endorse harassment or assault, especially sexual assault, and also less likely to change their behavior, apart from relinquishing hobbies, activities, or group participation, compared with their respective counterparts. These differences are expected to affect bipartisan support for anti-harassment legislation; necessitating the need for future research on sexual harassment to include participant political information. Research efforts should also aim to explore how and why these differences arise as there are no obvious explanations for the noted discrepancy in victimization. Understanding the gap between political groups regarding sexual harassment experiences and responses may help promote a dialogue on the issue and foster national consensus that sexual harassment and assault is not to be tolerated.

We were thus unable to examine differences in reactions by harassment type and or generational effects. All data were self-report and therefore subject to participant reporting bias or memory inaccuracies. Data collection also occurred at two time points 4 days apart and did not include a lifetime exposure to violence measure. It is recommended that surveys on sexual harassment and assault be administered at a single time point and inquire about personal trauma history to improve methodological rigor and better adjust for differences in reporting and reactions to sexual victimization.
Sexual harassment and assault have become a core issue in contemporary society. Fueled by the 2017 #MeToo social media campaign, public discourse surrounding issues of harassment and assault are increasingly common and political. Based on our findings, we note that party differences do in fact arise when considering reporting and responses to sexual harassment and or assault. On average, Republicans and conservatives are less likely to endorse harassment or assault, especially sexual assault, and also less likely to change their behavior, apart from relinquishing hobbies, activities, or group participation, compared with their respective counterparts. These differences are expected to affect bipartisan support for anti-harassment legislation; necessitating the need for future research on sexual harassment to include participant political information. Research efforts should also aim to explore how and why these differences arise as there are no obvious explanations for the noted discrepancy in victimization. Understanding the gap between political groups regarding sexual harassment experiences and responses may help promote a dialogue on the issue and foster national consensus that sexual harassment and assault is not to be tolerated.

From 2017... Under-reporting of total energy intake is a common and well-known source of measurement error in dietary assessment; this bias is particularly significant in obese individuals
From 2017... People with a body mass index ⩾30 under-report their dietary intake: A systematic review. Helena Wehling, Joanne Lusher. Journal of Health Psychology, July 21, 2017. https://doi.org/10.1177/1359105317714318
Abstract: Under-reporting of total energy intake is a common and well-known source of measurement error in dietary assessment, and evidence suggests that this bias is particularly significant in obese individuals. After a multi-stage selection process of eligible papers, this literature review appraised 34 papers detailing the accuracy of self-reported dietary intake in people with an obese body mass index (BMI ⩾ 30). The available literature to date shows that having a body mass index ⩾30 is associated with significant under-reporting of food intake. Future research should look into identifying effective techniques to reduce this bias in clinical practice.

Masters Athletes and chess players reported a lower prevalence of chronic disease
Masters or pawns? Examining injury and chronic disease in male Masters Athletes and chess players compared to population norms from the Canadian Community Health Survey. Shruti Patelia, Rachael C. Stone, Rona El-Bakri, Mehrnaz Adli & Joseph Baker. European Review of Aging and Physical Activity, volume 15, Article number: 15 (2018).
Abstract
Background: Identifying the optimal type and amount of activity for the maintenance of function in older adults has proved challenging. On the one hand, Masters Athletes have been proposed as the ideal model of successful aging but most of this research has focused on physical functioning. On the other hand, the importance of cognitive engagement has been emphasized, which may be more strongly related to activities such as playing chess. The current study aimed to compare physical health outcomes (i.e., prevalence of physical injury and chronic disease) among older athletes and chess players. Masters Athletes and chess players were recruited from track and field and chess competitions within the province of Ontario. In addition to these primary groups, moderately active and inactive older adults from Canadian Community Health Survey were also included for comparison.
Results: Masters Athletes had significantly higher rates of injury with the lowest rates of chronic disease, compared to all other activity groups. In contrast, chess players reported lower rates of injury compared to Masters Athletes as well as lower prevalence of chronic diseases compared to the moderately active and inactive groups. The normative groups reported the lowest rate of injury, but increased prevalence of chronic diseases compared to Masters Athletes and chess players.
Conclusions: Findings from this study indicate that both athletic and cognitive engagement may be positively related to the physical health of older adults, since Masters Athletes and chess players reported a lower prevalence of chronic disease. Importantly, the results expand our current understanding of health by providing evidence for physical health outcomes associated with an activity that is primarily associated with cognitive health.

These synthetic husbands have an average income that is about 58% higher, & 30% more likely to be employed, than the actual unmarried men that are currently available to unmarried women
Mismatches in the Marriage Market. Daniel T. Lichter Joseph P. Price Jeffrey M. Swigert. Journal of Marriage and Family, September 4 2019. https://doi.org/10.1111/jomf.12603
Abstract
Objective: This article provides an assessment of whether unmarried women currently face demographic shortages of marital partners in the U.S. marriage market.
Background: One explanation for the declines in marriage is the putative shortage of economically attractive partners for unmarried women to marry. Previous studies provide mixed results but are usually focused narrowly on sex ratio imbalances rather than identifying shortages on the multiple socioeconomic characteristics that typically sort women and men into marriages.
Methods: This study identifies recent marriages from the 2008 to 2012 and 2013 to 2017 cumulative 5‐year files of the American Community Survey. Data imputation methods provide estimates of the sociodemographic characteristics of unmarried women's potential (or synthetic) spouses who resemble the husbands of otherwise comparable married women. These estimates are compared with the actual distribution of unmarried men at the national, state, and local area levels to identify marriage market imbalances.
Results: These synthetic husbands have an average income that is about 58% higher than the actual unmarried men that are currently available to unmarried women. They also are 30% more likely to be employed (90% vs. 70%) and 19% more likely to have a college degree (30% vs. 25%). Racial and ethnic minorities, especially Black women, face serious shortages of potential marital partners, as do low socioeconomic status and high socioeconomic status unmarried women, both at the national and subnational levels.
Conclusions: This study reveals large deficits in the supply of potential male spouses. One implication is that the unmarried may remain unmarried or marry less well‐suited partners.

Games of chance: A near miss is said to occur when feedback for a loss approximates a win (“cherry–cherry–lemon” on a slot machine); experiments failed to support the "near-miss effect" hypothesis
The Near-Miss Effect in Slot Machines: A Review and Experimental Analysis Over Half a Century Later. Jeffrey M. Pisklak, Joshua J. H. Yong, Marcia L. Spetch. Journal of Gambling Studies, September 14 2019. https://link.springer.com/article/10.1007/s10899-019-09891-8
Abstract: In games of chance, a near miss is said to occur when feedback for a loss approximates a win. For instance, obtaining “cherry–cherry–lemon” on a slot machine could be considered a near miss. Sixty-six years ago, B.F. Skinner first proposed the idea that near-miss events might reinforce continued play in slot machines, and despite some inconsistencies in the experimental literature, belief in this “near-miss effect” has remained strong. In the present manuscript, we will review this literature and present experimental assessments of the near-miss effect on the frequency of the gambling response. Experiment 1 used a tightly controlled resistance-to-extinction procedure in pigeons to evaluate the putative reinforcing effect of near misses relative to a control “far-miss” reel pattern. Experiment 2 extended Experiment 1’s procedure to human participants. The results of both experiments failed to support the near-miss effect hypothesis. Experiment 3 used a further simplified procedure to assess the validity of the resistance-to-extinction paradigm when a probable conditional reinforcer was present on the reel stimuli. Although a clear conditional response was obtained from the reel, subsequent testing in extinction revealed no conditionally reinforcing function of this stimulus on operant response frequency.

Body Images of Blind and Sighted Women: No differences with regard to physical contact, vitality, and self-exaltation; significantly higher self-acceptance of body in the blind group
Differences in the Body Images of Blind and Sighted Women. Carolin Gebauer, Verena Guenther and Kristina Stuerz. European Journal of Health Psychology, Volume 26, Issue 2, pp. 50-55, September 11, 2019. https://doi.org/10.1027/2512-8442/a000029
Abstract: This study addresses aspects of body image in blind versus seeing women. Eighty-nine congenitally blinded and 153 sighted women completed questionnaires to demographic, health-relevant data, and body image. The two groups did not differ significantly with regard to demographic and health-relevant data. However, significantly more women have children among the sighted group. All women generally presented as clinically inconspicuous in all factors of the body image. A group comparison does not reveal differences with regard to physical contact, vitality, and self-exaltation. However, a significantly lower sexual fulfillment among the blind persons in comparison to the seeing persons, but a significantly higher self-acceptance, is demonstrated. The results are discussed in the context of the previous scarce findings with regard to body image disorders in blind women and finally questioned whether they could benefit the therapy of body scheme disorders in seeing women.

How do People Perceive the Cleanliness and Morality of Someone who Expresses Inappropriate Disgust: Showing either too much or too little disgust is perceived to be immoral
Consequences of Agreement versus Disagreement on Physical Disgust: How do People Perceive the Cleanliness and Morality of Someone who Expresses Inappropriate Disgust. Maayan Katzir Matan Hoffman Nira Liberman. European Journal of Social Psychology, September 13 2019, https://doi.org/10.1002/ejsp.2631
Abstract: We examined how people perceived a person who expressed inappropriate physical disgust – a person who was either under‐disgusted by physically disgusting stimuli or over‐disgusted by neutral stimuli. Participants formed an impression of a target after receiving information on how s/he rated disgusting (Studies 1, 2) or neutral (Studies 2, 3) pictures, and disgusting or angering scenarios (Study 4). Studies 1, 2 and 4 found that a target person who failed to experience disgust was seen as disgusting, immoral (but only to the extent that s/he was also seen unclean), and not socially desirable. A target who rated neutral stimuli as disgusting was not judged as disgusting but was nevertheless judged as immoral and not socially desirable (Studies 2, 3). Our results show that a target whose judgments of physical disgust deviate from one's own by showing either too much or too little disgust is perceived to be immoral.

Instead of having an educative effect across contexts, the exposure to deterrence practices increases unethical behavior of fraudsters but also of non-fraudsters
Fabio Galeotti, Valeria Maggian, Marie Claire Villeval. Fraud Deterrence Institutions Reduce Intrinsic Honesty. 2019. halshs-02281894. https://halshs.archives-ouvertes.fr/halshs-02281894
Abstract: Deterrence institutions are widely used in modern societies to discourage rule violations but whether they have an impact beyond their immediate scope of application is usually ignored. Using a natural field experiment, we show that they affect intrinsic honesty across contexts. We identified fraudsters and non-fraudsters in public transport who were or not exposed to ticket inspections by the transport company. We then measured the intrinsic honesty of the same persons in a new unrelated context where they could misappropriate money. Instead of having an educative effect across contexts, the exposure to deterrence practices increases unethical behavior of fraudsters but also of non-fraudsters.

Meat reducers (those who reduce Meath consumption) are less satisfied with their diet than true vegetarians, maybe because of the more effort applied, the more rewarded they feel
Asher, Kathryn, and Paul Peters. 2019. “Go the Whole Nine Yards? How Extent of Meat Restriction Impacts Individual Dietary Experience.” SocArXiv. September 13. doi:10.31235/osf.io/ycbd2
Abstract: There are a variety of approaches to addressing meat overconsumption including forms of meat restriction that vary by the degree of reductions and the type of meat reduced. This study examines three such diets—a vegetarian diet, a reduced-meat diet, and a chicken-free diet—with a focus on the differences in the lived dietary experiences of their adherents. These lived experiences are operationalized using a variety of measures: satisfaction with food-related life, social ties, convenience, social/personal life, health, cost, motivation, identity, perception of prevalence rates, length of diet adherence, and the theory of planned behavior (intentions, attitudes, perceived behavioral control, and subjective norms). The data comes from an online survey of a cross-sectional, census-balanced sample of more than 30,0000 U.S. residents aged 18+ years sourced from Nielsen’s Harris Panel. The results showed meat reducers to be a larger group than previously suspected, with a third of American adults self-identifying as reducing their meat consumption, compared to one percent each who identify as a vegetarian or chicken avoider. The findings also demonstrated that a vegetarian diet had the strongest lived dietary experiences among American adults who are currently eating one of the meat-restricted diets. This research speaks to how the degree and type of meat restriction can impact an individual’s lived experience with their diet.

People Rely Less on Consumer Reviews for Experiential Than Material Purchases
People Rely Less on Consumer Reviews for Experiential Than Material Purchases. Hengchen Dai, Cindy Chan, Cassie Mogilner. Journal of Consumer Research, ucz042, September 10 2019. https://doi.org/10.1093/jcr/ucz042
Abstract: An increasingly prevalent form of social influence occurs online where consumers read reviews written by other consumers. Do people rely on consumer reviews differently when making experiential purchases (events to live through) than when making material purchases (objects to keep)? Though people often use consumer reviews both when making experiential and material purchases, an analysis of more than 6 million reviews on Amazon.com and four laboratory experiments reveal that people are less likely to rely on consumer reviews for experiential purchases than for material purchases. This effect is driven by beliefs that reviews are less reflective of the purchase’s objective quality for experiences than for material goods. These findings not only inform how different types of purchases are influenced by word-of-mouth, but they illuminate the psychological processes underlying shoppers’ reliance on consumer reviews. Furthermore, as one of the first investigations into how people choose among various experiential and material purchase options, these findings suggest that people are less receptive to being told what to do than what to have.

When in middle childhood, no differences emerged as a function of parental sexual orientation in observations or self-reports of coparenting; & parents & teachers described children as well-adjusted overall
Farr, R. H., Bruun, S. T., & Patterson, C. J. (2019). Longitudinal associations between coparenting and child adjustment among lesbian, gay, and heterosexual adoptive parent families. Developmental Psychology, http://dx.doi.org/10.1037/dev0000828
Abstract: This longitudinal study examined coparenting and child adjustment during early and middle childhood (Ms = 3 and 8 years, respectively) among 106 lesbian, gay, and heterosexual parent adoptive families. When children were in middle childhood, no differences emerged as a function of parental sexual orientation in observations or self-reports of coparenting; in addition, parents and teachers described children as well-adjusted overall. After controlling covariates, including couple relationship adjustment, more supportive coparenting in early childhood predicted fewer parent-reported child internalizing and externalizing problems in middle childhood. Within middle childhood, stronger parenting alliance was associated with fewer parent-reported child externalizing problems. These findings indicate the value of considering family processes among diverse families in contributing to child outcomes over time.

Most school shooters were not previously treated with psychotropic medications – and even when they were, no direct or causal association was found
The myth of school shooters and psychotropic medications. Ryan Chaloner Winton Hall Susan Hatters Friedman Renee Sorrentino Maria Lapchenko Adeyemi Marcus Robert Ellis. Behavioral Sciences & the Law, September 12 2019. https://doi.org/10.1002/bsl.2429
Abstract: There has been an assertion in certain parts of the media, especially social media, that the majority of individuals who have engaged in a school shooting were prescribed psychotropic medications prior to the event. To determine if there is any validity to this assertion, the authors of this article reviewed publicly available information regarding individuals involved in “educational shootings” per FBI publications for active shooters from 2000 to 2017. Sources of information included news reports with official citations, official reports regarding events, available court records, and FBI Freedom of Information Act requests. Secondary data‐points were also collected, such as location, number of weapons used, number of victims, legal outcome, and whether the shooter committed suicide. From the information obtained, it appears that most school shooters were not previously treated with psychotropic medications – and even when they were, no direct or causal association was found.

Evidence of the intergenerational transmission of child maltreatment (“maltreatment begets maltreatment,”: Effect sizes seems real but modest
Testing the cycle of maltreatment hypothesis: Meta-analytic evidence of the intergenerational transmission of child maltreatment. Sheri Madigan et al. Development and Psychopathology, Volume 31, Special Issue 1 (The effect of maltreatment experiences on maltreating and dysfunctional parenting: A search for mechanisms), February 2019 , pp. 23-51. https://doi.org/10.1017/S0954579418001700
Abstract: It has long been claimed that “maltreatment begets maltreatment,” that is, a parent's history of maltreatment increases the risk that his or her child will also suffer maltreatment. However, significant methodological concerns have been raised regarding evidence supporting this assertion, with some arguing that the association weakens in samples with higher methodological rigor. In the current study, the intergenerational transmission of maltreatment hypothesis is examined in 142 studies (149 samples; 227,918 dyads) that underwent a methodological quality review, as well as data extraction on a number of potential moderator variables. Results reveal a modest association of intergenerational maltreatment (k = 80; d = 0.45, 95% confidence interval; CI [0.37, 0.54]). Support for the intergenerational transmission of specific maltreatment types was also observed (neglect: k = 13, d = 0.24, 95% CI [0.11, 0.37]; physical abuse: k = 61, d = 0.41, 95% CI [0.33, 0.49]; emotional abuse: k = 18, d = 0.57, 95% CI [0.43, 0.71]; sexual abuse: k = 18, d = 0.39, 95% CI [0.24, 0.55]). Methodological quality only emerged as a significant moderator of the intergenerational transmission of physical abuse, with a weakening of effect sizes as methodological rigor increased. Evidence from this meta-analysis confirms the cycle of maltreatment hypothesis, although effect sizes were modest. Future research should focus on deepening understanding of mechanisms of transmission, as well as identifying protective factors that can effectively break the cycle of maltreatment.

Ridesharing: Socially superior outcomes may involve monopoly or competition under various multihoming regimes, depending on the density of the city
Bryan, Kevin and Gans, Joshua S., A Theory of Multihoming in Rideshare Competition (July 27, 2018). SSRN: http://dx.doi.org/10.2139/ssrn.3208616
Abstract: We examine competition amongst ridesharing platforms, where firms compete on both price and the wait time induced with idled drivers. We show that when consumers are the only agents who multihome, idleness is lower in duopoly than when consumers face a monopoly ridesharing platform. When drivers and consumers multihome, idleness further falls to zero as it involves costs for each platform that are appropriated, in part, by their rival. Interestingly, socially superior outcomes may involve monopoly or competition under various multihoming regimes, depending on the density of the city, and the relative costs of idleness versus consumer disutility of waiting.

When drivers and consumers multihome, idleness further falls to zero as it involves costs for each platform that are appropriated, in part, by their rival. Interestingly, socially superior outcomes may involve monopoly or competition under various multihoming regimes, depending on the density of the city, and the relative costs of idleness versus consumer disutility of waiting.

The cooperative sex: Sexual interactions among female bonobos are linked to increases in oxytocin, proximity and coalitions
The cooperative sex: Sexual interactions among female bonobos are

https://doi.org/10.1016/j.yhbeh.2019.104581
Highlights
• Female bonobos have more frequent sex with female than male partners in feeding contexts.
• Female dyads are more likely than inter-sexual dyads to remain close after sex.
• Female urinary oxytocin levels increase following sex with females, but not with males.
• Dyads that have more sex engage in more joint coalitionary aggression.
• Sex among female bonobos may facilitate cooperation via oxytocinergic effects.
Abstract: In some species habitual same-sex sexual behavior co-occurs with high levels of intra-sexual alliance formation, suggesting that these behaviors may be linked. We tested for such a link by comparing behavioral and physiological outcomes of sex with unrelated same- and opposite-sex partners in female bonobos (Pan paniscus). We analyzed behavioral outcomes following 971 sexual events involving n = 19 female and n = 8 male adult and sub-adult members of a wild, habituated bonobo community. We additionally collected n = 143 urine samples before and after sexual interactions to non-invasively measure oxytocin (OT), which modulates female sexual behavior and facilitates cooperation in other species. The majority of sexual events (65%) consisted of female same-sex genito-genital rubbing (or GG-rubbing). Female dyads engaged in significantly more sexual interactions than did inter-sexual dyads, and females were more likely to remain within close proximity to their partners following GG-rubbing. Females also exhibited greater increases in urinary OT following GG-rubbing compared with copulations, indicating a physiological basis for increased motivation to cooperate among females. The frequency of coalitionary support among non-kin was positively predicted by the frequency of sexual interactions for female as well opposite-sex dyads, although coalitionary support tended to be more frequent among females. The emergence of habitual same-sex sexual behavior may have been an important step in the evolution of cooperation outside of kinship and pair-bonds in one of our closest phylogenetic relatives

Those who are interested in politics, who feel that they have a moral duty to vote in elections, and who feel close to a party are more prone to be satisfied with their decision to vote and to be dissatisfied if they chose to abstain
From 2017... Was my decision to vote (or abstain) the right one? André Blais, Fernando Feitosa, Semra Sevi. Party Politics, July 20, 2017. https://doi.org/10.1177/1354068817722058
Abstract: This article examines people’s assessments, ex post, of whether their decision to vote or to abstain in a given election was the right one. We use 22 surveys conducted in 5 different countries (Canada, France, Germany, Spain and Switzerland) in national, supra-national and sub-national elections between 2011 and 2015. We find that the great majority of those who voted were satisfied with their decision to vote while non-voters were more doubtful about the wisdom of their decision to abstain. We also find that those who are interested in politics, who feel that they have a moral duty to vote in elections, and who feel close to a party are more prone to be satisfied with their decision to vote and to be dissatisfied if they chose to abstain.

Search Advertising and Information Discovery: Are Consumers Averse to Sponsored Messages? Seems not so much.
Sahni, Navdeep S. and Zhang, Charles, Search Advertising and Information Discovery: Are Consumers Averse to Sponsored Messages? (August 23, 2019). SSRN: http://dx.doi.org/10.2139/ssrn.3441786
Abstract
We analyze a large-scale field experiment conducted on a US search engine in which 3.3 million users were randomized into seeing more, or less advertising. Our data rejects that users are, overall, averse to search advertising targeted to them. At the margin, users prefer the search engine with higher level of advertising. The usage of the search engine (in terms of number of searches, and number of search sessions) is higher among users who see higher levels of advertising, relative to the control group. This difference in usage persists even after the experimental treatment ends. The increase in usage is higher for users on the margin who, in the past, typed a competing search engine's name in the search query and navigated away from our focal search engine. On the supply side, higher level of advertising increases traffic to newer websites. Consumer response to search advertising is also more positive when more businesses located in the consumer's state create new websites. Quantitatively, the experimental treatment of a higher level of advertising increases ad clicks which leads to between 4.3% to 14.6% increase in search engine revenue.
Overall, patterns in our data are consistent with an equilibrium in which advertising conveys relevant “local” information, which is unknown to the search engine, and therefore missed by the organic listings algorithm. Hence, search advertising makes consumers better off on average. On the margin, the search engine does not face a trade-off between advertising revenue and search engine usage.

We exhibit a bias to accept incoming information, because most claims in our environments are true; and we interpret feelings, like ease of processing, as evidence of truth, regardless of intelligence level or cognitive style
Judging Truth. Nadia M. Brashier and Elizabeth J. Marsh. Annual Review of Psychology, Vol. 71:- (Volume publication date Jan 2020), September 12, 2019. https://doi.org/10.1146/annurev-psych-010419-050807
Abstract: Deceptive claims surround us, embedded in fake news, advertisements, political propaganda, and rumors. How do people know what to believe? Truth judgments reflect inferences drawn from three types of information: base rates, feelings, and consistency with information retrieved from memory. First, people exhibit a bias to accept incoming information, because most claims in our environments are true. Second, people interpret feelings, like ease of processing, as evidence of truth. And third, people can (but do not always) consider whether assertions match facts and source information stored in memory. This three-part framework predicts specific illusions (e.g., truthiness, illusory truth), offers ways to correct stubborn misconceptions, and suggests the importance of converging cues in a post-truth world in which falsehoods travel further and faster than the truth.

The experiments and paradigms that purportedly demonstrate spontaneous perspective-taking have not as yet convincingly demonstrated the existence of such a phenomenon
The closing of the theory of mind: A critique of perspective-taking. Geoff G. Cole, Abbie C. Millett. Psychonomic Bulletin & Review, September 12 2019. https://link.springer.com/article/10.3758/s13423-019-01657-y
Abstract: Theory of mind (ToM) is defined as the ability to attribute mental states to oneself and others and is often said to be one of the cornerstones of efficient social interaction. In recent years, a number of authors have suggested that one particular ToM process occurs spontaneously in that it is rapid and outside of conscious control. This work has argued that humans efficiently compute the visual perspective of other individuals. In this article, we present a critique of this notion both on empirical and theoretical grounds. We argue that the experiments and paradigms that purportedly demonstrate spontaneous perspective-taking have not as yet convincingly demonstrated the existence of such a phenomenon. We also suggest that it is not possible to represent the percept of another person, spontaneous or otherwise. Indeed, the perspective-taking field has suggested that humans can represent the visual experience of others. That is, going beyond assuming that we can represent another’s viewpoint in anything other than symbolic form. In this sense, the field suffers from the same problem that afflicted the “pictorial” theory in the mental imagery debate. In the last section we present a number of experiments designed to provide a more thorough assessment of whether humans can indeed represent the visual experience of others.

Patients locked in state suffering from amyotrophic lateral sclerosis: Cognitively intact, are completely paralyzed, eyes mostly closed, artificial ventilation & artificial nutrition, but we found a surprisingly healthy sleep pattern

Steffen Gais. Sleep, zsz185, August 2 2019,
https://doi.org/10.1093/sleep/zsz185
Abstract: Persons in the completely locked in state (CLIS) suffering from amyotrophic lateral sclerosis (ALS) are deprived of many zeitgebers of the circadian rhythm: While cognitively intact, they are completely paralyzed, eyes mostly closed, with artificial ventilation and artificial nutrition, and social communication extremely restricted or absent. Polysomnographic recordings in 8 patients in CLIS however revealed the presence of regular episodes of deep sleep during night time in all patients. It was also possible to distinguish an alpha-like state and a wake-like state. Classification of REM sleep is difficult because of absent eye movements and absent muscular activity. 4 out of 8 patients did not show any sleep spindles. Those who have spindles also show K-complexes and thus regular phases of sleep stage 2. Thus, despite some irregularities we found a surprisingly healthy sleep pattern in these patients.

Online media can induce opinion polarization even among users exposed to ideologically heterogeneous views, by heightening the emotional intensity of the content
Thinking Fast and Furious: Emotional Intensity and Opinion Polarization in Online Media. David Asker, Elias Dinas. Public Opinion Quarterly, nfz042, September 9 2019, https://doi.org/10.1093/poq/nfz042
Abstract: How do online media increase opinion polarization? The “echo chamber” thesis points to the role of selective exposure to homogeneous views and information. Critics of this view emphasize the potential of online media to expand the ideological spectrum that news consumers encounter. Embedded in this discussion is the assumption that online media affects public opinion via the range of information that it offers to users. We show that online media can induce opinion polarization even among users exposed to ideologically heterogeneous views, by heightening the emotional intensity of the content. Higher affective intensity provokes motivated reasoning, which in turn leads to opinion polarization. The results of an online experiment focusing on the comments section, a user-driven tool of communication whose effects on opinion formation remain poorly understood, show that participants randomly assigned to read an online news article with a user comments section subsequently express more extreme views on the topic of the article than a control group reading the same article without any comments. Consistent with expectations, this effect is driven by the emotional intensity of the comments, lending support to the idea that motivated reasoning is the mechanism behind this effect.

Violent Video Game Content & Aggressive Behaviour: Effect sizes are alike the sizes of significant yet nonsense effects of Extra Sensory Perception
Drummond, Aaron, and James D. Sauer. 2019. “Divergent Meta-analyses Do
Not Present Uniform Evidence That Violent Video Game Content Increases
Aggressive Behaviour.” PsyArXiv. September 13. doi:10.31234/osf.io/xms5u
Abstract: Whether violent games increase aggression is a contentious issue. The relatively enduring disagreement in the literature about whether violent video games cause increased aggression is reflected in divergent meta-analyses. Though we applaud Mathur and VanderWeele (2019) for attempting to synthesise such divergent meta-analyses to determine an overarching view on the effects of violent media, we argue that their interpretation of the evidence is misguided. Underpinning the notion that the evidence, in general, favours a “violent game effect” lie two problematic assumptions: (a) that the analyses conducted within these meta-analyses are equally methodologically and statistically rigorous and therefore equally valid, and (b) that even tiny effects are veridical. Here, we show that the effects reported by Anderson et al. (2010) appear to overstate the evidence in favour of a relationship between violent game content and aggression, and that bias-corrected models produce only tiny effects (Hilgard et al., 2017). We then compare these smaller effects estimated by Hilgard et al. (2017) and Ferguson (2015) to show that they appear to be in close agreement. Finally, as a reminder that non-zero meta-analytic effect sizes do not guarantee that an effect is meaningful, we compare these effect sizes to the sizes of (significant) yet nonsense effects of Extra Sensory Perception to show that the effects of violent game content on aggression are so small that we should dismiss them as practically meaningless.

From 2017... Participants, particularly women, avoided receiving attractiveness feedback more when the ratings came from high-threat evaluators (university peers) than from low-threat evaluators (older adults, children)
From 2017... Hot or not? How self-view threat influences avoidance of attractiveness feedback. Jennifer L. Howell, Kate Sweeny, Wendi Miller & James A. Shepperd. Self and Identity, Volume 18, 2019 - Issue 2, Pages 144-158, Dec 10 2017. https://doi.org/10.1080/15298868.2017.1401552
Abstract: In two studies, we examined whether people’s decision to receive evaluations of their own attractiveness depended on whether the evaluations came from sources that might threaten their self-views. Participants believed that evaluators rated their attractiveness based on a photograph taken earlier and ostensibly uploaded to a website. Participants then received the opportunity to view the attractiveness ratings from the evaluators. In both studies, and in a meta-analysis including two pilot studies that are reported in Supplemental Materials online, participants – particularly women – rated feedback as more threatening and avoided receiving feedback more when the ratings came from high-threat evaluators (university peers) than from low-threat evaluators (students at another university, older adults, or children). The robustness of this overall effect was confirmed in the meta-analysis. These results suggest that self-view threat can prompt information avoidance.

Some developmental theories of intelligence posit that gains in crystallized intelligence depend mainly on fluid intelligence but also on a range of so-called intellectual investment traits, like Openness to Experience and interest
Should students be smart, curious, or both? Fluid intelligence, openness, and interest co-shape the acquisition of reading and math competence. Clemens M. Lechner, Ai Miyamoto, Thomas Knopf. Intelligence, Volume 76, September–October 2019, 101378. https://doi.org/10.1016/j.intell.2019.101378
Highlights
• Fluid intelligence, Openness, and interest co-shape reading and math competence
• Fluid intelligence and subject-specific interests interact synergistically
• Interest has more pervasive effects than Openness
• Findings are highly similar for both domains, reading and math
• Results confirm and extend developmental models of intelligence
Abstract: Developmental theories of intelligence in the tradition of Cattell's investment theory posit that gains in crystallized intelligence (gc) depend mainly on fluid intelligence (gf) but also on a range of so-called intellectual investment traits, such as Openness to Experience and interest in a subject area. However, the relative predictive power of, and the precise nature of the interplay between, gf and different intellectual investment traits remains incompletely understood. In this study, we use large-scale, multi-wave data on secondary school students from the German National Educational Panel Study (NEPS; N = 4646) to investigate how gf, Openness, and subject-specific interest relate to baseline levels and change over two years in gc in two domains, reading and math. Results of latent-variable models revealed that gf and interest, and to a lesser extent, Openness, predicted higher initial levels and stronger gains over two years in reading competence and mathematical competence. Moreover, results yielded strong support for the notion that gf interacts synergistically with interest in reading and math in producing (gains in) reading competence and mathematical competence. In other words, gf and interest cross-fertilize each other, with students who have both high gf and high interest showing the highest rate of skill and knowledge acquisition. Our findings contribute to developmental theories of intelligence by providing further support for the claim that gf and intellectual investment traits are both essential for the development of gc—and by showing that the interplay between gc and investment traits is interactive and synergistic in nature.

Relative to industrialized populations, men from subsistence groups exhibit lower testosterone values and more modest declines with age; paper discusses reasons for these lower values
A Comparison of men’s Life History, Aging, and Testosterone Levels among Datoga Pastoralists, Hadza Foragers, and Qom Transitional Foragers. Louis Calistro Alvarado et al. Adaptive Human Behavior and Physiology, September 12 2019. https://link.springer.com/article/10.1007/s40750-019-00116-1
Abstract
Objectives: Relative to industrialized populations, men from subsistence groups exhibit lower testosterone values and more modest declines with age. Limited energy availability has been hypothesized to suppress testosterone production, particularly during young adulthood when testosterone levels are highest, resulting in a flatter trajectory of age-decline. Energetic constraint, however, is not unique to the evolutionary ecology of humans, and yet significant age-related testosterone decline is observed in numerous species of wild primates. Conversely, human life history is distinguished by extensive bi-parental care and male provisioning. Because fathers show decreased testosterone with parenting effort, we argue that within more naturalistic and evolutionarily relevant ecologies, natural fertility and earlier reproduction suppresses testosterone in emerging adulthood such that a lower relative baseline dictates less age-decline across the remaining lifespan.
Methods: We examine men’s testosterone levels as contrasting functions of energetic status and paternal involvement across three traditional populations with substantial variability in men’s nutritional condition and parental investment. Anthropometric and demographic data along with saliva samples were collected from 70 Datoga, 29 Hadza, and 43 Qom men, ages 20–72 years.
Results: Population variation in salivary testosterone was greatest at younger ages and patterned so paternal involvement associated with lower morning and evening testosterone, along with diminished age-decline in both measures. Men’s energetic status as indicated by body mass index was not associated with testosterone values or age-related decline.
Conclusions: Within socioecological contexts of smaller scale society, these data suggest that blunted age-decline in men’s testosterone levels is primarily due to population variation in parental investment rather than energetic constraint.

There is evidence that naturally cycling women in their fertile phase, compared to their luteal phase, evaluate specific behavioral cues in men as more attractive for sexual relationships; but this effect is not reproducible
Stern, Julia, Tanja M. Gerlach, and Lars Penke. 2018. “Probing Ovulatory Cycle Shifts in Women’s Preferences for Men’s Behaviors.” PsyArXiv. March 1. doi:10.31234/osf.io/7g3xc
Abstract: The existence of ovulatory cycle shifts in women’s mate preferences has been discussed controversially. There is evidence that naturally cycling women in their fertile phase, compared to their luteal phase, evaluate specific behavioral cues in men as more attractive for sexual relationships. However, recent research has cast doubt on these findings. We addressed this debate in a large, pre-registered within-subject study including salivary hormone measures and luteinizing hormone tests. One-hundred-fifty-seven female participants rated natural videos of 70 men in dyadic intersexual interactions on sexual and long-term attractiveness. Multilevel comparisons across two ovulatory cycles indicated that women’s mate preferences for men’s behaviors did not shift across the cycle, neither for competitive, nor for courtship behavior. Within-women hormone levels and relationship status did not affect these results. Hormonal mechanisms and implications for estrus theories are discussed.
Abstract: The existence of ovulatory cycle shifts in women’s mate preferences has been discussed controversially. There is evidence that naturally cycling women in their fertile phase, compared to their luteal phase, evaluate specific behavioral cues in men as more attractive for sexual relationships. However, recent research has cast doubt on these findings. We addressed this debate in a large, pre-registered within-subject study including salivary hormone measures and luteinizing hormone tests. One-hundred-fifty-seven female participants rated natural videos of 70 men in dyadic intersexual interactions on sexual and long-term attractiveness. Multilevel comparisons across two ovulatory cycles indicated that women’s mate preferences for men’s behaviors did not shift across the cycle, neither for competitive, nor for courtship behavior. Within-women hormone levels and relationship status did not affect these results. Hormonal mechanisms and implications for estrus theories are discussed.
How Virtue Signalling Makes Us Better: Moral Preferences with Respect to Autonomous Vehicle Type Choices
Kopecky, Robin, Michaela Košová, Daniel D. Novotný, Jaroslav Flegr, and David Černý. 2019. “How Virtue Signalling Makes Us Better: Moral Preferences with Respect to Autonomous Vehicle Type Choices.” PsyArXiv. September 11. doi:10.31234/osf.io/36vzk
Abstract
Autonomous vehicles (henceforth AVs) are expected to significantly benefit our transportation systems, their safety, efficiency, and impact on environment. However, many technical, social, legal, and moral questions and challenges concerning AVs and their introduction to the mass market still remain. One of the pressing moral issues has to do with the choice between AV types that differ in their built-in algorithms for dealing with situations of unavoidable lethal collision. In this paper we present the results of our study of moral preferences with respect to three types of AVs: (1) selfish AVs that protect the lives of passenger(s) over any number of bystanders; (2) altruistic AVs that minimize the number of casualties, even if this leads to death of passenger(s); and (3) conservative AVs that abstain from interfering in such situations even if it leads to the death of a higher number of subjects or death of passenger(s). We furthermore differentiate between scenarios in which participants are to make their decisions privately or publicly, and for themselves or for their offspring. We disregard gender, age, health, biological species and other characteristics of (potential) casualties that can affect the preferences and decisions of respondents in our scenarios. Our study is based on a sample of 2769 mostly Czech volunteers (1799 women, 970 men; age IQR: 25-32). The data come from our web-based questionnaire which was accessible from May 2017 to December 2017. We aim to answer the following two research questions: (1) Whether the public visibility of an AV type choice makes this choice more altruistic and (2) which type of situation is more problematic with regard to the altruistic choice: opting for society as a whole, for oneself, or for one’s offspring.
Our results show that respondents exhibit a clear preference for an altruistic utilitarian strategy for AVs. This preference is reinforced if the AV signals its strategy to others. The altruistic preference is strongest when people choose software for everybody else, weaker in personal choice, and weakest when choosing for one’s own child. Based on the results we conclude that, in contrast to a private choice, a public choice is considerably more likely to pressure consumers in their personal choice to accept a non-selfish solution, making it a reasonable and relatively cheap way to shift car owners and users towards higher altruism. Also, a hypothetical voting in Parliament about a single available program is less selfish when the voting does not take place in secret.

Adults with no siblings reported significantly lower levels of conscientiousness & honesty-humility & higher levels of neuroticism and openness than adults with siblings, but mean differences failed to reach the small effect size
Only Children in the 21st Century: Personality Differences between Adults With and Without Siblings are Very, Very Small. Samantha Stronge et al. Journal of Research in Personality, September 10 2019, 103868. https://doi.org/10.1016/j.jrp.2019.103868
Highlights
• Tested differences in HEXACO personality for adults with and without siblings.
• Gender and age interactions were non-significant for all traits.
• ‘Only children’ reported lower conscientiousness and honesty-humility.
• ‘Only children’ reported higher neuroticism and openness to experience.
• However, all mean differences failed to reach the threshold of a small effect size.
Abstract: Negative beliefs about only children suggest that they are spoiled and unlikable, with these early personality differences persisting across the lifespan. Early research found little support for the idea, yet, negative views towards only children remain prevalent. The current research re-visited the issue using a large national panel study of New Zealand adults (N = 20,592) to assess mean differences in personality between those with and without siblings. Adults with no siblings reported significantly lower levels of conscientiousness and honesty-humility and higher levels of neuroticism and openness than adults with siblings; however, mean differences failed to reach the threshold of even a small effect size (|d’s| = .08 - .11). Beliefs about only children appear to contradict actual group differences.

Their orgasms were less pleasurable compared to other experiences, and suggested that their orgasm experiences had negative impacts on their relationships, sexuality, and/or psychological health
When Orgasms Do Not Equal Pleasure: Accounts of “Bad” Orgasm Experiences During Consensual Sexual Encounters. Sara B. Chadwick, Miriam Francisco, Sari M. van Anders. Archives of Sexual Behavior, September 11 2019. https://link.springer.com/article/10.1007/s10508-019-01527-7
Abstract: Orgasms during consensual sex are often assumed to be wholly positive experiences. This assumption overshadows the possibility that orgasm experiences during consensual sex could be “bad” (i.e., negative and/or non-positive). In the present study, we employed an online survey to explore the possibility that orgasm experiences could be “bad” during consensual sex by asking participants of diverse gender and sexual identities (N = 726, M age = 28.42 years, SD = 7.85) about a subset of potential bad orgasm experiences. Specifically, we asked participants whether they have ever had an orgasm during coerced sex, compliant sex, and/or when they felt pressured to have an orgasm (i.e., orgasm pressure). We also asked participants who had such an experience to describe it, resulting in qualitative descriptions from 289 participants. Using mixed quantitative and qualitative analyses, we found compelling evidence that orgasm experiences can be “bad” during consensual sex. Specifically, many participants described their experiences in negative and/or non-positive ways despite orgasm occurrence, reported that their orgasms were less pleasurable compared to other experiences, and suggested that their orgasm experiences had negative impacts on their relationships, sexuality, and/or psychological health. Participants also suggested that social location shaped their bad orgasm experiences, citing gender and sexual identity, gender identity conflict, race/ethnicity, and religion as important to their perceptions of and responses to their experiences. Results directly challenge the assumption that orgasms during consensual sex are always and/or unilaterally positive experiences.

Influence of experience on the performance of police criminal risk assessment of juveniles: Significantly higher accuracy of risk assessment, but accuracy did not increase with experience
Influence of experience on the performance of police criminal risk assessment of juvenile offenders. Barbara Bergmann. Forensische Psychiatrie, Psychologie, Kriminologie, Jul 2 2019. https://doi.org/10.1007/s11757-019-00552-5
Abstract: Police officers working in the field of juvenile crime have to assess the criminal risk of young offenders before admitting them into a special police program for chronic offenders. Their performance of this task, which is mostly based on mere experience, has so far been unclear. The following study examined the process of criminal risk assessment in the police context and tested if performance increases with growing experience. The test sample consisted of 85 police officers and 60 undergraduate psychology students as laypersons. The task was to examine fictitious case vignettes of young criminals and rate their risk of further offences. Performance was measured by accuracy of the given rating and the time needed to evaluate each vignette. Results showed a significantly higher accuracy of risk assessment made by police officers when compared to laypersons; however, within the group of police officers the accuracy did not increase with experience. Nevertheless, particularly experienced police officers seemed to use a more efficient strategy as they considered less information for their assessment and thus needed less time to come to a conclusion. These findings indicate an advanced information processing due to experience resulting in a reduction of the cognitive workload and time needed for the assessment.

Twitter: meta-features like the number of followers of the author, the count of tweets produced and the ratio of tweet number and days since account creation affect credibility judgments
The Impact of Twitter Features on Credibility Ratings-An Explorative Examination Combining Psychological Measurements and Feature Based Selection Methods. Judith Meinert, Ahmet Aker, Nicole C. Krämer. Proceedings of the 52nd Hawaii International Conference on System Sciences, Jan 2019. https://scholarspace.manoa.hawaii.edu/bitstream/10125/59698/0258.pdf
Abstract: In a post-truth age determined by Social Media channels providing large amounts of information of questionable credibility while at the same time people increasingly tend to rely on online information, the ability to detect whether content is believable is developing into an important challenge. Most of the work in that field suggested automated approaches to perform binary classification to determine information veracity. Recipients ́ perspectives and multidimensional psychological credibility measurements have rarely been considered. To fill this gap and gain more insights into the impact of a tweet ́s features on perceived credibility, we conducted a survey asking participants (N=2626) to rate the credibility of crisis-related tweets. The resulting 24.823 ratings were used for an explorative feature selection analysis revealing that mostly meta-related features like the number of followers of the author, the count of tweets produced and the ratio of tweet number and days since account creation affect credibility judgments.

The effect of stress on economic rationality: Rationality is not impaired by the stressor; if anything, participants are more consistent with rationality immediately after the stressor
Cortisol meets GARP: the effect of stress on economic rationality. E. Cettolin et al. Experimental Economics, September 11 2019. https://link.springer.com/article/10.1007/s10683-019-09624-z
Abstract: Rationality is a fundamental pillar of Economics. It is however unclear if this assumption holds when decisions are made under stress. To answer this question, we design two laboratory experiments where we exogenously induce physiological stress in participants and test the consistency of their choices with economic rationality. In both experiments we induce stress with the Cold Pressor test and measure economic rationality by the consistency of participants’ choices with the Generalized Axiom of Revealed Preference (GARP). In the first experiment, participants delay the decision-making task for 20 min until the cortisol level peaks. We find significant differences in cortisol levels between the stressed group and the placebo group which, however, do not affect the consistency of choices with GARP. In a second experiment, we study the immediate effect of the stressor on rationality. Overall, results from the second experiment confirm that rationality is not impaired by the stressor. If anything, we observe that compared to the placebo group, participants are more consistent with rationality immediately after the stressor. Our findings provide strong empirical support for the robustness of the economic rationality assumption under physiological stress.

Prisoner’s Dilemma game: Participants were more cooperative when they saw each other compared to when they could not, and when receiving reliable compared to unreliable or no feedback
The Interplay Between Face-to-Face Contact and Feedback on Cooperation During Real-Life Interactions. Friederike Behrens, Mariska E. Kret. Journal of Nonverbal Behavior, September 11 2019. https://link.springer.com/article/10.1007/s10919-019-00314-1
Abstract: Cooperation forms the basis of our society and becomes increasingly essential during times of globalization. However, despite technological developments people still prefer to meet face-to-face, which has been shown to foster cooperation. However, what is still unclear is how this beneficial effect depends on what people know about their interaction partner. To examine this question, 58 dyads played an iterated Prisoner’s Dilemma game, sometimes facing each other, sometimes without face contact. Additionally, explicit feedback regarding their decisions was manipulated between dyads. The results revealed that participants were more cooperative when they saw each other compared to when they could not, and when receiving reliable compared to unreliable or no feedback. Contradicting our hypothesis that participants would rely more on nonverbal communication in the absence of explicit information, we observed that the two sources of information operated independently on cooperative behavior. Interestingly, although individuals mostly relied on explicit information if available, participants still cooperated more after their partner defected with face-to-face contact compared to no face-to-face contact. The results of our study have implications for real-life interactions, suggesting that face-to-face contact has beneficial effects on prosocial behavior even if people cannot verify whether their selfless acts are being reciprocated.

participants still cooperated more after their partner defected with faceto-face-contact. Hence, people might be more "forgiving" when facing their partner when he/she defects and theefore encourage the defecting partner to return to cooperation by opting for a cooperative decision themselves.

Investigating the Dynamic Relationship of Emotions and Attention Toward Political Information With Mobile Experience
Only One Moment in Time? Investigating the Dynamic Relationship of Emotions and Attention Toward Political Information With Mobile Experience Sampling. Lukas P. Otto et al. Communication Research, September 10, 2019. https://doi.org/10.1177/0093650219872392
Abstract: This article attempts to (a) investigate the relationship between distinct emotional reactions toward political information and attention toward political news and (b) analyze whether this relationship is dynamic. We use an experience sampling design to assess recipients’ immediate emotional reactions and attention toward news. Participants reported their emotional reactions (anger, fear, happiness, contentment) and attentional focus directly after following a news item for 8 days in a row up to 5 times a day via smartphone. Results indicate that anger is positively and fear negatively correlated with attention toward political news. For positive emotional reactions, happiness is not correlated with attention to news, while contentment is negatively correlated with attention and also shows a negative lagged effect on attention at a later point in time. The study shows promising ways to assess and analyze dynamic processes in everyday media consumption.

We are all saints and sinners: Some of our actions benefit other people, while other actions harm people. How do people balance moral rights against moral wrongs when evaluating others’ actions?
Johnson, Samuel G. B., and Jaye Ahn. 2019. “Principles of Karmic Accounting: How Our Intuitive Moral Sense Balances Rights and Wrongs.” PsyArXiv. September 10. doi:10.31234/osf.io/xetwg
Abstract: We are all saints and sinners: Some of our actions benefit other people, while other actions harm people. How do people balance moral rights against moral wrongs when evaluating others’ actions? Across 9 studies, we contrast the predictions of three conceptions of intuitive morality—outcome- based (utilitarian), act-based (deontologist), and person-based (virtue ethics) approaches. Although good acts can partly offset bad acts—consistent with utilitarianism—they do so incompletely and in a manner relatively insensitive to magnitude, but sensitive to temporal order and the match between who is helped and harmed. Inferences about personal moral character best predicted blame judgments, explaining variance across items and across participants. However, there was modest evidence for both deontological and utilitarian processes too. These findings contribute to conversations about moral psychology and person perception, and may have policy implications.

Under low budget conditions, Eastern & Western participants differed in their mate dollar allocation for almost every trait (culture influences prioritization); but the same priorities were given for traits needed for reproductive success
Mate preference priorities in the East and West: A cross‐cultural test of the mate preference priority model. Andrew G. Thomas et al. Journal of Personality, September 8 2019. https://doi.org/10.1111/jopy.12514
Abstract
Objective: Mate choice involves trading‐off several preferences. Research on this process tends to examine mate preference prioritization in homogenous samples using a small number of traits and thus provide little insight into whether prioritization patterns reflect a universal human nature. This study examined whether prioritization patterns, and their accompanying sex differences, are consistent across Eastern and Western cultures.
Method: In the largest test of the mate preference priority model to date, we asked an international sample of participants (N = 2,477) to design an ideal long‐term partner by allocating mate dollars to eight traits using three budgets. Unlike previous versions of the task, we included traits known to vary in importance by culture (e.g., religiosity and chastity).s
Results: Under low budget conditions, Eastern and Western participants differed in their mate dollar allocation for almost every trait (average d = 0.42), indicating that culture influences prioritization. Despite these differences, traits fundamental for the reproductive success of each sex in the ancestral environment were prioritized by both Eastern and Western participants.
Conclusion: The tendency to prioritize reproductively fundamental traits is present in both Eastern and Western cultures. The psychological mechanisms responsible for this process produce similar prioritization patterns despite cross‐cultural variation.

We compare how much food others are eating as compared to our portions, what types of foods they eat, dimensions related to eating such as body weight & shape & other dimensions like social status
C. Peter Herman, Janet Polivy, Patricia Pliner, Lenny R. Vartanian. Social Influences on Eating pp 147-162, September 6 2019. https://link.springer.com/chapter/10.1007/978-3-030-28817-4_9
Abstract: A large literature shows that people compare themselves to others on a wide variety of dimensions; this is called social comparison. Such comparisons to other people can provide useful guides for our behavior, and they may also have emotional consequences, affecting our self-esteem and happiness. We compare ourselves to others with respect to our food consumption as well as other behaviors related to eating. For example, we compare how much food others are eating as compared to our portions, what types of foods others eat, dimensions related to eating such as body weight and shape and even dimensions not directly related to eating such as social status. Such food-related social comparisons can affect not only our eating but our emotions and other behaviors as well. We want to “look good,” act appropriately, and be treated fairly, relative to others, and social comparisons around food and eating are important contributors to this.

Abstract: An individual’s knowledge is collective in at least two senses: it often comes from other people’s testimony, and its deployment in reasoning and action requires accuracy underwritten by other people’s knowledge. What must one know to participate in a collective knowledge system? Here, we marshal evidence that individuals retain detailed causal information for a few domains and coarse causal models embedding markers indicating that these details are available elsewhere (others’ heads or the physical world) for most domains. This framework yields further questions about metacognition, source credibility, and individual computation that are theoretically and practically important. Belief polarization depends on the web of epistemic dependence and is greatest for those who know the least, plausibly due to extreme conflation of others’ knowledge with one’s own.

When outdated norms are used, the Flynn Effect inflates IQs and potentially biases intellectual disability diagnosis; a Flynn Effect was found for IQs ≥ 130, and a negative effect for IQs ≤ 70
The Flynn effect for fluid IQ may not generalize to all ages or ability levels: A population-based study of 10,000 US adolescents. Jonathan M. Platt et al. Intelligence, Volume 77, November–December 2019, 101385. https://doi.org/10.1016/j.intell.2019.101385
Highlights
• When outdated norms are used, the Flynn Effect inflates IQs and potentially biases intellectual disability diagnosis
• In a large US-representative adolescent sample, a Flynn Effect was found for IQs ≥ 130, and a negative effect for IQs ≤ 70
• IQ changes also differed substantially by age group
• A negative Flynn Effect for those with low intellectual ability suggests widening disparities in cognitive ability
• Findings challenge the practice of generalizing IQ trends based on data from non-representative samples
Abstract: Generational changes in IQ (the Flynn Effect) have been extensively researched and debated. Within the US, gains of 3 points per decade have been accepted as consistent across age and ability level, suggesting that tests with outdated norms yield spuriously high IQs. However, findings are generally based on small samples, have not been validated across ability levels, and conflict with reverse effects recently identified in Scandinavia and other countries. Using a well-validated measure of fluid intelligence, we investigated the Flynn Effect by comparing scores normed in 1989 and 2003, among a representative sample of American adolescents ages 13–18 (n = 10,073). Additionally, we examined Flynn Effect variation by age, sex, ability level, parental age, and SES. Adjusted mean IQ differences per decade were calculated using generalized linear models. Overall the Flynn Effect was not significant; however, effects varied substantially by age and ability level. IQs increased 2.3 points at age 13 (95% CI = 2.0, 2.7), but decreased 1.6 points at age 18 (95% CI = −2.1, −1.2). IQs decreased 4.9 points for those with IQ ≤ 70 (95% CI = −4.9, −4.8), but increased 3.5 points among those with IQ ≥ 130 (95% CI = 3.4, 3.6). The Flynn Effect was not meaningfully related to other background variables. Using the largest sample of US adolescent IQs to date, we demonstrate significant heterogeneity in fluid IQ changes over time. Reverse Flynn Effects at age 18 are consistent with previous data, and those with lower ability levels are exhibiting worsening IQ over time. Findings by age and ability level challenge generalizing IQ trends throughout the general population.
Genetic and Environmental Influences on Different Forms of Bullying Perpetration, Bullying Victimization, and Their Co-occurrence: Genes play a large role
Genetic and Environmental Influences on Different Forms of Bullying Perpetration, Bullying Victimization, and Their Co-occurrence. Sabine A. M. Veldkamp et al. Behavior Genetics, September 10 2019. https://link.springer.com/article/10.1007/s10519-019-09968-5
Abstract: Bullying comes in different forms, yet most previous genetically-sensitive studies have not distinguished between them. Given the serious consequences and the high prevalence of bullying, it is remarkable that the aetiology of bullying and its different forms has been under-researched. We present the first study to investigate the genetic architecture of bullying perpetration, bullying victimization, and their co-occurrence for verbal, physical and relational bullying. Primary-school teachers rated 8215 twin children on bullying perpetration and bullying victimization. For each form of bullying, we investigated, through genetic structural equation modelling, the genetic and environmental influences on being a bully, a victim or both. 34% of the children were involved as bully, victim, or both. The correlation between being a bully and being a victim varied from 0.59 (relational) to 0.85 (physical). Heritability was ~ 70% for perpetration and ~ 65% for victimization, similar in girls and boys, yet both were somewhat lower for the relational form. Shared environmental influences were modest and more pronounced among girls. The correlation between being a bully and being a victim was explained mostly by genetic factors for verbal (~ 71%) and especially physical (~ 77%) and mostly by environmental factors for relational perpetration and victimization (~ 60%). Genes play a large role in explaining which children are at high risk of being a victim, bully, or both. For victimization this suggests an evocative gene-environment correlation: some children are at risk of being exposed to bullying, partly due to genetically influenced traits. So, genetic influences make some children more vulnerable to become a bully, victim or both.
